Histogram - registry.histogram(metadata) - IllegalArgumentException ------------------------------------------------------------------- Key: WFLY-11459 URL: https://issues.redhat.com/browse/WFLY-11459 Project: WildFly Issue Type: Bug Components: MP Metrics Affects Versions: 15.0.0.Final Reporter: Rostislav Svoboda Priority: Critical Fix For: 18.0.0.Beta1, 18.0.0.Final Histogram - registry.histogram(metadata) returns IllegalArgumentException on second invocation of the endpoint. The same app works fine on Open Liberty. JavaDoc of public abstract Histogram histogram(Metadata metadata); says {{@return a new or pre-existing Histogram}} so on second invocation I should get the pre-existing histogram. https://github.com/smallrye/smallrye-metrics/issues/42
